A 32-year-old San Francisco man has been charged with murder for allegedly stabbing his mother to death at their home in Oceanview, according to authorities.

Islam Moustafa is facing murder and assault with a deadly weapon charges in connection with the fatal stabbing of 65-year-old Hoda Nasar near Randolph and Victoria streets last Friday night.

The District Attorney’s Office filed the charges against Moustafa on Tuesday. The murder charge includes an additional allegation for using a deadly weapon.

Moustafa and Nasar were both plaintiffs in a civil court lawsuit that identified them as relatives and tenants of 333 Randolph St.

The lawsuit, which was settled before trial in December 2016, alleged that their landlord did not maintain the property and harassed them.

The lawsuit also alleged that the landlord ran a gambling den called “the Shack” out of the basement of their home until summer 2014, resulting in drug use and fighting at the property.

Moustafa was booked into County Jail.

Nasar was the second homicide victim in San Francisco this year.

Manuel Valladares, a 35-year-old San Francisco resident who was shot and killed near Union Square early Sunday morning, was the third victim.

Valladares was shot near Mason and Geary streets at around 4:41 a.m., according to police. Valladares was taken to a local hospital with a gunshot wound and died.

Police have not released a detailed description of the suspect.

The first homicide of 2018 happened last Thursday when police found a 59-year-old man stabbed and bleeding from the neck and torso on Potrero Avenue and 24th Street.
The Medical Examiner’s Office later identified the man as Mark Camacho of San Francisco.

Police arrested 48-year-old Jesus Ramirez, also a San Francisco resident, in connection with the homicide last Friday. He was booked into County Jail on suspicion of murder.

Both Ramirez and Moustafa are scheduled to be arraigned Wednesday.
